Every so often, an adjustment to one's asset allocation seems prudent. These days, as I noted, it just "leaps off the page". I've throttled back this year on equities, but, even so, my YTD is up over 17% at Vanguard. Mind you, this was hardly a full-throated allocation to equities. I have (and have added to) VBTLX and VBIAX. Even so, the YTD keeps going up. This, my friends, is scary, and the potential sign of a market top. Is this market-timing? Perhaps. But if, and only if, you intend to plop the harvest back in later. I don't.
Contrarian investors, as am I, see flashing red lights. For those with out-sized gains in Mr. Market this year, rotation of at least part of those gains (the "harvest") might be prudent. Several options: (a) bond funds. While dicey in a rising-rate environment, the risk is much less than equities in a bear market; (b) cash. Returns stink; (c) CDs, my preferred option. Harvest those gains, and, if possible, ladder them into 5-year CDs.
Folks, it's a casino out there. Remember what your Mom told you. "Walk out the door while you have chips in your pocket. If you don't, never mind trying to call me for bus fare."
